Entropy theorems in classical mechanics, general relativity, and the gravitational two-body problem
Marius Oltean, Luca Bonetti, Alessandro D. A. M. Spallicci +1
In classical Hamiltonian theories, entropy may be understood either as a statistical property of canonical systems, or as a mechanical property, that is, as a monotonic function of…
Vacuum fluctuation of conformally coupled scalar field in FLRW space-times
Giovanni Acquaviva, Luca Bonetti, Luciano Vanzo +1
The regularized vacuum fluctuation related to a conformally coupled massless scalar field defined on a space-time with dynamical horizon is computed with respect a radially moving…
Ray tracing in FLRW flat space-times
Giovanni Acquaviva, Luca Bonetti, Guido Cognola +1
In this work we take moves from the debate triggered by Melia et al [9]. and followed by opposite comments by Lewis and Oirschot [10,11]. The point in question regards the role of…
